I am even more off-topic, and of course this was only an example. But this reference sounds so positive, yet this really is no forward technology that you quote, touring along several hundred kilogram of batteries that is. Already at the end of the eighties i think (the usual ")everybody(") knew that fuel cells are the future. It is true that i have said in a local auditorium in 1993 that i wished with 18 everybody would get a underfloor with fuel cells in the sandwich that it is, and four wheel hub motors, and a minimalistic structure that one may replace at will. It was already possible back then (but for superior tightness of the tank), just like, for example, selective cylindre deactivation, diesel soot filter, diesel NOx reduction cat ("urea injection"). (Trying to clean Diesel in the uncertain conditions that multi-million engines at different heights and climate are in is megalomaniacal, in my opinion. And that already back then.) Unfortunately fuel cell development has never been politically pushed as much as desirable, and was mostly up to universities until at least about 2006, and in Germany, to the best of my knowledge. It may not be popular in the U.S. at the moment, but it is Toyota again, with the Mirai, who spends money due to responsibility. That is at least what i think. (And again it is the question whether a doubtful technology is spread millions and millions of times all over the place, or whether only some refineries have to be improved.) --steffen
